Looking for a wake surf board for bigger riders. I'm 6'0 260lbs, Decent rider. i currently own a shredd stix but doesn't have the speed I'm looking for. I can get the current board to release and can stick a 360 from time to time. just looking for something faster and quicker release, if it is available for larger riders.

Which stixx model do you currently ride? In general, you will need to look at a custom board sized more for you.

I would suggest a custom Shred Stixx Ringer in the 4'11" to 5'0" range.

Similarly sized TWPs or soulcrafts will also fit the bill.

On the production end (of the shelf) there are a number of board capable and designed for riders in your size range. Below are a few that are faster and more maneuverable:
Shred Stixx Headband
Inland Flyboy (big)

i am a 395 lbs rider. i ride a walker project bazooka. my buddy rides a walker bomp pop. if i was you i could email the walker project and let them know your size and how you ride and what kind of wave you are riding and they will fit you to what they make. and they can alter there boards to fit you since they are 100% hand made. not factory pressed bull ****. they just came out with a super bomp pop. this winter i am going to have them make me a hybrid bazooka/supper bomp pop. let denis know paul the big guy from washington on the bazooka sent you.
